Hard-disk password
There are two hard-disk passwords (HDPs):
v User HDP—for the user
v Master HDP—for the system administrator, who can use it to get access to the
hard disk even if the user has changed the user HDP
Note:
There are two modes for the HDP: User only and Master + User. The
Master + User mode requires two HDPs; the system administrator enters both in
the same operation. The system administrator then provides the user HDP to the
system user.
Attention:
If the user HDP has been forgotten, check whether a master HDP has
been set. If it has, it can be used for access to the hard disk drive. If no master
HDP is available, neither Lenovo nor Lenovo authorized servicers provide any
services to reset either the user or the master HDP, or to recover data from the
hard disk drive. The hard disk drive can be replaced for a scheduled fee.
For how to remove the POP, see “How to remove the hard-disk password” on
page 36.
Supervisor password
A supervisor password (SVP) protects the system information stored in the BIOS
Setup Utility. The user must enter the SVP in order to get access to the BIOS Setup
Utility and change the system configuration.
Attention: If the SVP has been forgotten and cannot be made available to the
servicer, there is no service procedure to reset the password. The system board
must be replaced for a scheduled fee.
How to remove the power-on password
To remove a POP that you have forgotten, do the following:
(A) If no SVP has been set:
1. Turn off the computer.
2. Remove the battery pack.
For how to remove the battery pack, see “1010 Battery pack” on page 60.
3. Remove the backup battery.
For how to remove the backup battery, see “1090 Backup battery” on page 77.
4. Turn on the computer and wait until the POST ends.
After the POST ends, the password prompt does not appear. The POP has been
removed.
5. Reinstall the backup battery and the battery pack.
(B)
If an SVP has been set and is known by the servicer:
1. Turn on the computer.
2. When the ThinkPad logo comes up, immediately press F1 to enterBIOS Setup
Utility.
